I reached across beneath the cow to attach a metal bail to each end of the strap so that the bail hung about 5 inches below the cow's belly. […] While stroking and talking to the cow, I reached under and suspended the machine on the bail beneath the cow, with its four suction cups dangling to one side.

More recently, the fixed bail, sometimes called the ‘milking parlour’, with either covered or open yards, has had a certain vogue and some very enthusiastic claims have been made for this method of housing.

But until he had poured enough milk into the vat above the separator, I drove unmilked cows into the bail where he had previously milked and released one. He moved from one bail to the other to milk the next one I had readied. I drove each cow into the empty bail, chained her in, roped the outer hind leg then washed and massaged the udder and teats.
